PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 729,850, dated June 2, 1903.

Application filed August 16, 1902. Serial No. 119,852. (No model. 7

To aZZ whom it may concern:

Be it known that LLAWRENCE'L. DUERDEN, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, and city and State of New York, have invented certain new and useful Improvements in Pa per Boxes, of which fication.

This invention relates to the class of knockdown boxes which may be folded fiat for packing and shipping, to be afterward'folded into form for use as required; and the purpose of the'invention is to provide a box composed of two simple rectangular pieces which provide the sides, ends, bottom, cover, and tucks of the box.

In the accompanying drawings, which serve to illustrate an embodiment of the invention, Figure 1 is a perspective view of one element or part of the box, and Fig. 2 is a similar view of the other element or part. Fig. 3 is a per spective view showing the parts put together and partly folded. Fig. 4 is a perspective view of the folded box formed of the said two elements or parts. Fig. 5 is a cross-section of the folded box at the line 00 in Fig. 4. Fig.- 6 illustrates the box provided with a liningpiece. Fig. 7 is a view similar to Fig. 1, showing the part B provided with a locking-flap to provide a more secureconnection between the parts A and B; and Fig. 8 is an enlarged detail View illustrating this feature.

A designates as a whole one of the two elethe followingis a speciments or parts of the box, and B designates the other part. The part A is merely a rectangular sheet of paper-board, preferablycellular board, creased transversely to form a securing-flap 1, the box-bottom 2, a box side 3, the box-cover 4;, and a tuck5. The part B is also a rectangular sheet of the same material, creased transversely to form two closing end flaps 6, the two box ends7, and a box side 8. In the upper edge of the side 8 is formed a recess 9 to permit the thumb or finger to get access to the tuck 5 for opening the box.

In cutting and creasing the parts A and B the part A is cut a little wider than the length of the side 8 of the part B for reasons that will be apparent when the setting up of the box is explained.

'so as to clamp endwise the fiap 1.

In setting up the box the flap 1 is placed against the inner face of the box side 8, as seen in Fig. 3, and the box ends 7 7 folded in, The side 3 is now folded up against the outer faces of the flaps 6 6, the cover 4 folded over the top, and the flap 5 tucked in. The box will then present the appearance seen in Fig. 4.

It will be noted that it is the clasping end- -wise and edgewise of the end flap 1 and also the tuck 5 and fiaps 6 which holds the sections firmly together, and this construction is especially adapted to what is known as "cellular board, composed of two plain sheets of paper with a corrugated sheet pasted between them. It will also be noted that a box of this character may be out without waste may have, if desired, an inner lining-piece C,

Fig. .6, secured to the bottom 3 of the part or section A. This is also a plain rectangular sheet creased crosswise,so as to form a box like lining of fiveparts or flaps, as clearly shown. This lining-piece may be secured to the bot tom 3 by any securing means, as paste or wire staples s, for example. When the box of Fig. 6 is folded, the part 10- of the lining will be applied to the box-bottom 2, the parts 11 11 thereof to ends of the box, and the parts or flaps 12 12 to the cover of the box.

Figs. 7 and 8 show the same box as that illustrated in the other figures, but with the slight addition of what I call locking-flaps 13 on the ends 7 of the box. When the box is folded, these flaps 13 bear at their ends upon the flap 1 and press it firmly against the inner face of the box side 8' to assist in holding together the two parts A andB. Indeed, if the box be made from the relatively thick cellular board-(see Fig. 8) the end of the flap 13 may be made to indent the material of the flap 1 or crush it in, so as to'make the look very secure. The partB may-have other short flaps 14, (seen in Fig. 7;) but these are not very important. In cutting out the sheet B these flaps may be left on without any loss of material, as the sheet must be wide enough to provide the flaps 13. Fig. 7 shows only one of the flaps 13; but there will be by preference one on each of the box ends 7.

It will be noted that my box has these two characteristics-namely, the two rectangular parts A and B are normally flatthat is, neither is folded and joined at its ends to form a frame, as in some kinds of two-part boxes; there is no exterior frame to hold the two parts when they are interlocked to form a box; the two parts are bound together or interlocked solely by the edgewise clamping of the flaps of one part by the flat sides or faces of the embracing part, and no paste or other adhesive material is employed or necessary.

Having thus described my invention, I claim- 1. A paper box consisting of but two separate creased and folded, but primarily flat sections, the creases of one section being disposed at right angles with those of the other section, and the sections held together in box-like form solely by compression between the flat faces of the embracing section and the edges of the flaps on the section embraced, substantially as set forth.

2. A paper box consisting of but two separate creased and folded, but primarily flat rectangular sections, the said sections being applied to each other with the creases of one at right angles to those of the other and held together in box-like form solely by the compression edgewise of a flap or flaps of one section by the flat faces of embracing flaps on the other section, substantially as set forth.

3. A paper box consisting of but two separate and primarily fiat sections, A and B, creased to form the bottom, top, sides, ends, flaps and tucks of the box, said sections being applied with the creases of one section disposed at right angles to those of the other, and having, as the means of securing the two sections together in box-like form, a flap 1 on one section clamped edgewise between the inner faces of the embracing parts 7 of the other section, whereby the parts are held together in box-like form solely by compression, substantially as set forth.

4. A paper box consisting of two, primarily fiat and separate, folded, rectangular sections A and B, creased to form the bottom, top, sides, ends, flaps and tucks of the box, the flap l on the section A being clamped forcibly edgewise between the inner faces of the ends 7 on the other section and the flaps 6 on the section B being clamped forcibly edgewise between the inner faces of the top and bottom on the other section, substantially as set forth.

In witness whereof I have hereunto signed my name, this 11th day of August, 1902, in the presence of two subscribing Witnesses.
